Primarily for general aviation discussion, but other aviation topics are also welcome.
Sorry but I can't link the Yahoo story but it appears to have involved cruise ship passengers on a sightseeing flight. From the article there are multiple casualties.

Three people were still missing, US Coast Guard and Federal Aviation Administration officials said.

The two aircrafts involved were an Otter float plane carrying 11 people and a Beaver float plane with five people on board.

A passenger on the Princess Cruise revealed an announcement was made at 6.30pm saying four fellow guests had died, nine were in hospital and one was missing.
